[2.13] What goes down must come up (in part): What are we learning from Chandra about warm outflows in AGN?

About two-thirds of type I AGN exhibit outflows of warm, ionized gas from the central accreting regions. The location, origin and dynamics of the warm outflows are still poorly understood. The new generation of X-ray telescopes, such as Chandra, allow us to study the warm outflows with unprecedented spectral resolution. Here we present results from a survey of the warm absorbing gas in 15 type I AGN observed with the high energy gratings on board Chandra. We are beginning to see hints of correlations which may illuminate the origins of the warm outflow and the accretion processes in the central engine of the AGN.
